one common negative side effect of orthodontic treatment with fixed appliances is the development of incipient caries lesions around brackets, particularly in patients with poor oral hygiene. different methods have been used to prevent demineralization such as fluoride therapy and application of sealant to prevent caries. the recent effort to improve the resistance against the demineralization ...
laser-tissue interaction is of great interest due to its significant application in biomedical optics in both diagnostic and treatment purposes. major aspects of the laser-tissue interaction which has to be considered in biomedical studies are the thermal properties of the tissue and the thermal changes caused by the interaction of light and tissue. in this review paper the effects of light on ...
Background and Aims : Free gingival graft is one of the most predictable procedures for gingival augmentation, but patient’s discomfort and pain during healing period of palatal donor site is a significant concern. The aim of this study was to evaluate the effect of 660nm low power laser on pain and healing in palatal donor sites. Materials and Methods: The present split mouth randomized co...
objectives: fluoride therapy is important for control and prevention of dental caries. laser irradiation can increase fluoride uptake especially when combined with topical fluoride application. the objective of this study was to compare the effects of co 2 and diode lasers on enamel fluoride uptake in primary teeth. materials and methods: forty human primary molars were randomly assigned to fou...
peri-implantitis is one of the most common reasons for implant failure. decontamination of infected implant surfaces can be achieved effectively by laser irradiation; although the associated thermal rise may cause irreversible bone damage and lead to implant loss. temperature increments of over 10ºc during laser application may suffice for irreversible bone damage.the purpose of this study was ...
Background: knee osteoarthritis is one of the most common causes of chronic disability in the elderly. Despite the widespread application of low energy laser for pain treatment there is much controversy about its efficacy. The aim of this study was to investigate the analgesic effects of low energy laser in patients with knee osteoarthritis along with drug therapy and non - drug therapy in Tabr...
Background and aim: The scars of the cutaneous leishmaniasis and psychologic problems of this disease needs different intervention for its correction. Our objective in this study was to compare the efficacy of trichloroacetic acid (TCA) 50 percent solution and CO2 laser for treatment of the atrophic scars due to leishmaniasis. Materials and methods: This was a randomized clinical trial perfomed...
Purpose: The aim of present investigation was to evaluate low frequency low-level infra red diode laser therapy for a third degree burn healing in rats skin.Materials and Methods: 36 rats were divided into groups one and two. On day zero three third degree burns were made on the dorsum of each rat by steam. In group one ,first burn were exposed to a 80 Hz –pulsed 890 nm infra red diode laser wi...
